This manuscript provides an analyzes of a one-dimensional modeling approach for post-combustion
CO2 capture in a Hollow Fiber Membrane Contactor (HFMC), which uses a 30% (w/w) MEA
(monoethanolamine) solution as a solvent. A reactive absorption is considered, with variable gas and liquid
resistances. The influence of the volumetric rate (G°) on the system parameters was evaluated, and then, the system
behavior was studied, fixing the parameters to achieve a capture ratio of 90%. The MATLAB 2021a® software
was used to solve the equations, and a routine was created, allowing to solve the problem as an initial value problem
(IVP), which shown to be efficient.
